    Another good thing is a crontab job which makes a rotating gzipped copy of
    the db.  I shuffle from mud.db.0.gz through to mud.db.9.gz.  When pumping in
    a new copy, the .9 file drops off and get's lost, which is a good thing if
    you have a large db.

    You will want to remember to use nice when doing the gzip to avoid lag.
